Protecting the Electrical/Electronic Systems During Charging or Welding
WARNING
Battery acid causes burns. Batteries contain sulfuric acid.
Avoid contact with skin, eyes or clothing. Antidote (external): Flush with water. Antidote (eyes): flush
with water for 15 minutes and seek medical attention immediately. Antidote (internal): Drink large quan-
tities of water or milk. Do not induce vomiting. Seek medical attention immediately.
Failure to comply could result in death or serious injury.
To avoid damage to the electronic/electrical systems, always observe the following:
1. Never make or break any of the charging circuit connections, including the battery connections, when the engine
is running.
2. Never short any of the charging components to ground.
3. Always disconnect the ground cable from the battery before arc welding on the machine or on any machine
attachment.
• Position the welder ground clamp as close to the welding area as possible
• If welding near a computer module, remove the module from the machine.
• Never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding
is in progress
4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery
charger.
NOTICE: If welding must be performed on the unit, the battery ground cable must be disconnected from the machine
battery. The electronic monitoring system and charging system will be damaged if this is not done.
Remove the battery ground cable. Reconnect the cable when welding is completed.
